It's been a while since someone has sent us photos and video of their hot-rod home roaster. As the saying goes, good things come to those that wait, so when we got an email from Larry Cotton with this video of his machine, our jaws dropped.
Larry's machine roasts small amounts (about 3oz) at a time but it allows him to roast continuously without a lot of time lapsing between batches. The open basket gives him a full view of the roasting process which can be difficult with most home roasting machines. Larry says, "I originally wanted to build a continuous, set-and-forget roaster. Just keep the green-bean hopper full and unload the cool roasted beans at the other end. All prototypes failed in one way or the other--some quite spectacularly (mostly the "forget" part). So I decided to stay with the small-batch roasting process, but just speed it up. After much trial-and-mostly-error experimentation, I settled on a combination of a small propane campstove and a tilted, open-ended basket."
